though your girlfriend may have lied to you about things, i doubt she lied to you about this. there had to be many qualities about you that kept her around for two years. superficial people care about looks. is this the type of person you really want in your life? there are so many people in the world that do not measure up to the standard of looks you are talking about, yet they are still able to find life partners. it is because of their kindness, caring, compassion, humor, personality, etc. more people are concerned about these things than looks. so start focusing on your strenghts and feeling good about them. build strenght of caracter and soon you will find your phsycal presence doesnt matter anymore.
